Minor Changes

• #4739 8692912 Thanks @rcaplanshopify! - Expose extended address fields to checkout UI extensions:

  • Country.acceptedAddressInputFields (the buyer's current country; on checkout's Country only, not customer accounts') and localization.acceptedAddressInputFieldsForCountry(countryCode) (any country) list the address inputs a country's format carries, typed by the new AcceptedAddressInputField. They're guidance: applyShippingAddressChange doesn't reject a write because it includes fields outside the list. It still rejects unknown properties, wrong value types, missing approval scopes, a malformed addressLineComponents, components for a country without a component layout, and any addressCode write.
  • MailingAddress gains addressLineComponents (new AddressLineComponents type: streetName, streetNumber, additionalInformation, district, subdistrict) and addressCode.
  • applyShippingAddressChange accepts writes nested under addressLineComponents. ShippingAddressChangeFieldError.field is now ShippingAddressChangeErrorField, which widens keyof MailingAddress to include line component names and 'addressLineComponents'.
  • The address autocomplete suggest and format-suggestion targets receive target.acceptedAddressInputFields. AutocompleteAddress accepts addressLineComponents and addressCode.
  • @shopify/ui-extensions-tester: the checkout mock's localization.acceptedAddressInputFieldsForCountry() resolves the flat address input fields, and localization.country carries the same list. The new createAcceptedAddressInputFieldsForCountry(overrides?) helper and FLAT_ADDRESS_INPUT_FIELDS model countries with extended fields.

  Breaking for custom implementations: Localization has a new required method, and exhaustive checks on ShippingAddressChangeFieldError.field need the new members.

• #4715 e34b5a7 Thanks @js-goupil! - Add version to the POS Extension API. shopify.extension.version is the name of the published app version that the running extension was deployed in — the same name shown on the Versions page of the dev dashboard, and the name chosen when running shopify app deploy. Use it to tell which build of an extension a merchant is running, which POS can cache and run offline for some time after a newer version is deployed. It's an opaque name rather than a version number, so compare it for equality. It's undefined when the extension runs from a local development server, because a build that hasn't been deployed has no published version.

• #4690 3703a5b Thanks @ajanth-u! - Add the s-pos-list web component for POS and the posListTemplate tagged template that compiles its <s-pos-list-item> row markup.

• #4724 9f5ad67 Thanks @js-goupil! - Add the POS navigation navigatesuccess event type and documentation for listening after a screen finishes appearing.

Patch Changes

• #4737 9d07293 Thanks @ChemsCode! - Expose AuthenticatedAccountCustomer for the Authenticated Account API and its Preact hook, retaining Customer as a deprecated compatibility interface. Correct the customer ID documentation to describe a numeric string and use the public type names in the generated documentation.

• #4727 8ee0082 Thanks @henryStelle! - Remove stale POS component names from the component availability metadata for 2026-10 targets.

• #4683 8ebe439 Thanks @vctrchu! - Clarify POS validation interceptor and resolution event semantics, including cash amounts, empty results, revalidation updates, and generated interceptor and Resolution API documentation.

• #4735 565c318 Thanks @ajanth-u! - Shorten the s-pos-list property descriptions for rows, itemTemplates, and loadingMore, and stop listing defaults for rows and itemTemplates.
